HOG-SGRAPING MACHINE.

Specification of Letters Patent.

Patented Apr. 23, 322.

Application filed March 19, 1910. Serial No. 550,520.

To all whom 'it may concern:

Be it known that I, \Vrnm EMIL -POUL Mains, manufacturing engineer, asubject'of the King of Denmark, residing at Grenaa,

'Denmark, have invented a Hog-Scraping Machine, of which the following.is :flfull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof. i

This invention has regard to a machine by means of which the hair orbristlesare scraped oil the scalded carcasses of swine.

The machine is placed at the end of the scalding vat, and the carcass ispassed straight from the vet throughthe machine.

By using this machine a great deal of labor and time is saved, as themachine served one man completely removes the hair in about 25 seconds.

The drawing showsi Figure l the machine seen from the side with part ofthe large drum cut away, and Fig. 2 the machine seen from the end,pulleys anduniversal joint having been removed.

The large drum a, which rests on rollers 12- is started rotating by thecog Wheel f acting on a spur-Wheel Z, Which lies around the drum in sucha manner, that itholds toget-her the Wooden battens, of which the drumis composed. Inside the drum a number of angle irons 51 forming parallelribs, are arranged. These angle irons give a rotary motion, to thecarcass and at the same time guide it through the drum. \vVhile thecarcass is passing through the drum, it is scraped by a number ofsemi-circular scrapers c (60 for example) of galvanized plates, each ofwhich is attached to a spring, which again is fastened to a hexagonalroller Z), that is set rotating by a system of chain wheels.

The scrapingroller and its scrapers res upon the carcass under avariable pressure, the roller being balanced by means of two two-armedlevers d furnished with a sliding weight, and which turn around the'axle of the chain Wheel h.

The machine is used. in the following way: The scalded carcass slidesfrom the roller table 2' into the large drum, which revolves 25' times aminute, and comes under the scrap ing roller 6, which rotates in thecontrary direction. at a speed of 150 revolutions a minute. Therib-shaped angle irons 5 turn the carcass around, but the carcass alwaysremains at the bottom of the large drum and is acted upon by the springscrapers 0. During the whole process, which lasts about 25 seconds, thecarcass is played. upon by water and steam from the pipe which isfurnished with holes. The carcass then slides out on to another rollertable Z. and finished.

Having. now fully described my invention, what I claim and desire tosecure by Letters Phtent is:

A hog scraping machine, comprising an inclined rotatable drum, spirallyarranged ribs on the inside thereof, a roller inside of said drumsupported by the counterbalanced arms, said roller having its parallel.to

the axis of said drum, spring scrapers fitted on said roller, means forrotating the drum in one direction, means for. rotating the roller inthe other direction, means for feeding the carcass through the drum pastthe scraping roller, and means for ,d'scharging water and steam upon thecarcass during the scraping operaticn substantially as forth.

In testimony whereof I my signature
